Electronic Toy Batteries

[ViPER1313]

My cell battery (Li-ion) is 3 years old, I charge it up at the end of every day and it has never developed a memory - it will still go for 3 days or so before dying. I have never had the best of luck with Ni-MH batterys - they are really suceptable to overheating if your charger is too powerful and die quickly afterwords. In my experience, if you have AA or AAA rechargeables you can extend their life a lot by not using a quick charger - it seems to burn them out in short time.
